The RJ45 Crimper is one of the most popular and versatile tools available for networking professionals. You can use them to terminate cables, crimp connectors, pull wire through conduit or a wall, attach faceplates onto wires, and even strip cable jackets.

Some people think that with the high-speed connections we have these days, Ethernet crimping is a thing of the past. They’re wrong, though, because Ethernet cables are made to be durable and last, which means any compromised installation can cause disconnections in your system. 

An RJ45 crimper is a highly specialized kit and an essential tool for anyone involved in network engineering. You’d struggle to connect an Ethernet cable without one!

They work by puncturing the insulation of the network cable and fixing it into the RJ45 connectors, therefore allowing a connection between the copper wire and connector. There’s a nack to using them, but they are not limited to just professionals. They’re much more commonplace than ever, and a DIY’er could quickly learn to use one.

The biggest problem is the choice available, which can lead to indecision or purchasing one that is way too expensive for the users’ needs. We’ve tested and reviewed 5 of the best RJ45 Crimp tools on the market. One we assigned our Best Overall and another our Best Value pick. To make life easier for you, we’ve placed all 5 in an easy-to-read comparison table and have written a detailed buyers guide so you can assess your needs.

RJ45 Crimper Buyers Guide

As we mentioned in our introduction, this type of electrical work is specialized and not so long back, and it was left to professionals to do it. Things have changed with the introduction of some good value and well-performing tools and some online video tutorials. The price for each device ranges, and it doesn’t necessarily reflect the overall quality or even mean your connection will work. And that can be very frustrating!

Here are a few hints and tips to assist you in making the right purchasing decision.


RJ45 Crimpers


Modular connections

The three connectors your RJ45 crimper will have to be compatible with are the 4, 6, and 8 positions because these are the most common. Other configurations may mean you’ll need a tool compatible with more than the basic positions but look for a tool that can first work with the basic connectors.

Traditionally, you used RJ-45 cables on telephones and voice transfer, but technological advancements now mean their use is expanded. This means there are now category five and six connections, so make sure the crimper you buy is suitable for the connection you’re using.


The head of an RJ45 crimper is larger than the handle, and sometimes this can obscure your view, making it much more challenging to see your work. Network cabling is a refined skill and sometimes done in confined spaces, so if you have that requirement, look for a small and compact tool.


Some crimpers we reviewed came with a ratchet, allowing you to control the knobs’ tension better. This can be a good feature for a beginner as it’s too easy to cut the wire entirely instead of slicing it!

Type of cables

Some crimpers can work on round and flat cables, but you will need to check their specification if you need both, as not all models are compatible.


As with any tool, the purchase price is a factor as we all have a budget. We have found good models at low and high price brackets, and a high-priced item does not guarantee the crimper is better. Take, for example, the Klein tools crimper, where the cutter was pretty poor. This model was towards the more expensive end, and while it has excellent features, you’d expect it to be better at cutting than it is.

Ethernet crimping is delicate work, and our advice is to know precisely the type of work you need it for, how often you’ll be using it, and buy the model that fits your needs.
